Abstract

The invention concerns an arrangement of pumps and dispensers for highly viscous liquids with a high solids contents or a content of solids in larger segments, in particular for use with viscous foodstuffs. The substance to be delivered is supplied in a flexible, collapsible plastics container (1). The plastics container is inserted in a pressure vessel (3) connected to a pressure generator (4) which introduces a pressurized medium, in particular air or water, into the space between the plastics container and the pressure vessel. The substance to be delivered is discharged at the end of a delivery tube (7) connected in a pressure-tight manner to the plastics container. The delivery tube is associated with a squeezing device (10-13) comprising a plurality of functionally harmonized squeezing elements which force the substance to be delivered through the delivery tube. The resultant arrangement for discharging viscous liquids is structurally simple and ecological and has optimal microbiological properties.

Description

[Detailed description of the invention] Apparatus for pumping and distributing highly viscous liquids The present invention relates to a device for pumping and distributing highly viscous liquids. Highly viscous liquids and/or high solids content or relatively large The present invention relates to a device for pumping and dispensing comparable liquids containing finely divided solids.

Devices of the type described at the outset are suitable for use in the Federal Republic of Germany for common liquids, especially beverages. It is known from Japanese Patent Publication No. 22-61-798.

In the food industry there are often visual, sensory reasons and/or incompatibility. For reasons of nature, foreign products are first distributed immediately before their use. Looks like it's the same For reasons, especially since atmospheric oxygen often changes its properties, There are also problems in storing the products.

In the industrial field, the container capacity is usually 5 to 20 kg. At this time, packaging The container is used as a self-supporting container. For such a container , tin plate with a sticky closure for low and medium viscosity products. A can is used. Products with high viscosity, high solids content or relatively large particles For products containing debris, such containers are generally tubs or containers with spring lids. used. Flexible packaging containers, such as bags, are mainly used because their airtightness is inadequate. Only containers that can only be partially removed are used.

In an age when ecological issues are being questioned, containers that can be used many times are often used. It is. In particular, these packaging containers can be completely emptied. It is also attracting attention that it must be something that can be disposed of without polluting the environment. There is. For steel cans, especially those that are taken out several times. is completely empty (the question is whether it can be done or not and whether it has free capacity. Somewhat well-suited - 1 - tubs may be difficult to close under extreme conditions It is. For some reason, flat foil bags may wrinkle due to lack of strength. For reasons of Due to its small size, it is not suitable for use under rough handling conditions. This type of packaging The flexible bag that fits the container and the flexible bag that is provided as [-2] Most adaptable to different packaging requirements.

The transport and distribution of viscous and perishable products is primarily This is done using positive displacement compressors which are difficult to clean. The biggest bet of this pumping system I2 is The point is always in valve systems and packing systems where hardened grime tends to form. be. Centrifugal pumps without valves generate significantly large shear forces at pressure T. Therefore, depending on the circumstances, the composition of the transport medium may vary significantly. However, microbiology Which hose pump system is most suitable from the point of view of L or cleaning technology? On the one hand, the suction capacity is lacking, and on the other hand, the crushing roller There is no problem with the return moment of the transfer hose. Something similar This also applies to screw pumps known in large-scale industry.

Previously known distribution systems are particularly suitable for discharging and supplying mixed substances of different conveyances. It is not suitable for parallel discharge when the rods are installed in combination.

Especially in combinations of highly viscous liquids, such as ketchup, There is a drawback in that it requires significant changes in composition depending on manufacturing conditions. other high viscosity A liquid, such as margarine or melted cheese, changes its toughness with a slight change in temperature, i.e. The viscosity is significantly affected.

The placement of highly viscous liquids under variable working or environmental conditions is a critical issue. Ru. Traditional suction pumps or hose pumps - especially in the food industry In field use, the above problems cannot be easily solved. Particularly dependent on time control. It is not possible to perform the existing dosing with the desired precision.

However, precise positioning is necessary in many applications. in the food industry Is it not the application of grease lubrication or adhesive for the pole bearings? In applications to the placement of components of mixtures, dosing accuracy is particularly important for functionality. Ru.

The distribution of spices, for example, in sauces, takes into account taste-oriented or individual differences. Dosing accuracy in terms of minutes or additions, or for example mayonnaise for gelatup The accuracy of Ja arrangement with respect to the ratio of Considering business economic data 1 At 7, the amount of transferred material to be dispensed is important. Because from this amount, this arrangement This is because it is possible to result in the death of the main component mixed with the substance, t). child In this case, for example, it shows an example of the combination of toppings in a salad.

No hygienist problems - immediately detoxified sauce that should be thoroughly cleaned 1-' has already been mentioned. For groceries, the end of the transfer hose , generally at the end of the ejection element, which often leaves residual drops stuck to the special This is a problem. Such residual drops are a concern for cleanliness on the one hand and hygiene concerns on the other. Must be avoided for a reason. Generally slightly discolored due to air intrusion. The droplets have a large surface area compared to the cross section of the transfer hose and therefore It leads to uncleanness, especially from a microbiological point of view.

The underlying problem of the present invention is to solve the above problems and to provide an extremely simple structure. and the optimum characteristics taking into account ecological, sanitary and microbiological conditions and requirements. The object of the present invention is to provide a dispensing device of the type described at the outset, which has the following characteristics.

The above problem is solved by the configuration described in the characterizing part of claim 1.

Expression different from the description of the characteristic part of claim 1, in other words, The core of the solution is to operate within the transfer hose in an almost stepwise fashion or intermittently at appropriate times. A constant amount of transferred material is taken up and distributed by time control or by the configuration of the crushing member. be done. In the structure specified in both claims 2 and 6, one Claim 2) The arrangement comprises a number of collapse valves operated in a mutually matched manner. The other configuration (Claim 6) partially surrounds the transfer hose. It is based on a hose crushing pump.

Taking into account the above-mentioned problems regarding trailing droplet formation or droplet formation, each of the transfer cycles In the final phase, a negative pressure is generated at intervals on the end of the transfer hose. this As a result, most of the residue generated at the end of the transferred material is pushed back, leaving the end of the transfer hose (Claim 7).

A special arrangement taking into account the discharge of the transferred substance at the end of the transfer hose is covered by the claims. This is subject to the configurations described in Sections 9 and 10. These configurations allow the transfer hose to Opening on the end side into the distribution head, which distribution head is provided with a closing cap. (Claim 9) or as a cylindrical body with a closing rod (Claim 9). Claim 10). The distribution head has a large number of transfer channels. Is it possible to simultaneously distribute different transport substances through these transport lines? Ru.

In the configuration described above, if the distribution head is designed as a main shaft, the transported mass flow is Most are distributed in a twisted or intertwined manner.

The invention will now be described in detail with reference to the embodiments illustrated in the accompanying drawings.

The part shown in Figure 1I, which is a cross-sectional view taken along the cutting line X-X to explain the state, Figure 13 is a detailed view of the embodiment of the take-off tube for the synthetic substance container, Figure 13. Figure 14 shows an embodiment of the extraction lance for synthetic substance containers; Figure 15 shows the first Connection port for the take-out lance shown in Figure 4 or the connection port equipped with this take-out lance Four figures.

As shown in FIG. It is prepared in [vessel]. This synthetic container is filled with air bubbles to the brim as much as possible. It is filled to prevent it from growing. A mobile grip combined with such a container The combination enables environmentally conscious transport for consumers. This packaging style A particularly advantageous embodiment is described in patent application P39 04 080. consumption As shown in Figure 1, a flexible container l filled with filler material is heated. It is inserted into the pressure vessel 3. This synthetic substance container 1 is equipped with a filling and unloading connection 6. This filling and unloading connection is connected in a pressure-tight manner to the transfer hose 7.

The filling/unloading connection 6 is a cap that is locked to the pressurized container 3 by a bayonet closure. The outside is closed by a bar 2.

In the free air space between the synthetic substance container 1 and the pressurized container 3, a pressure generator 4 and a pressure reducer 5 are installed. A pressurized medium, especially compressed air or water, is introduced by the pressurizer, and a super pressurized P2 is formed. This super pressurization causes the flexible synthetic material container l to collapse (see arrow a), causing the brackets to collapse. The substance to be transferred is then forced into the transfer hose 7. The transfer hose 7 is straight at the end. The substance to be transported is discharged via contact or, if appropriate, a distribution head.

In the illustrated embodiment, along the transfer section, ie along the transfer hose 7, four Two hose-collapse valves 10.11.12.13 are provided. these hoses - the collapse valves are operatively connected to control valves 10', 11', 12', 13', respectively; ing. These control valves are themselves connected to a pressure generator 15 via a second pressure reducer 14. has been done. via this second pressure reducer 14 and the hose-collapse valve 10° The pressure applied through 1.13 is the superpressure P2 acting in the pressurized container 3. It has a relatively high pressure value P3 compared to . Control valves 10', , 13' are constant are operated in a mutually matched order. This allows the hose-collapse valve 10. ．． .

13 collapses the transfer hose 7 in a certain manner, causing the transfer hose 7 to collapse due to shrinkage of the synthetic material container 1. The material to be transferred which is pressurized into the hose 7 is divided and transferred to the end or starting end of the transfer hose 7. Apply pressure in the direction. In this way, the hose-collapse valve 10. ．． ．． Predetermined amount via 13 The volume of transferred substances allows for precise uptake, which is particularly dependent on external conditions. A purely hygienically or microbiologically accurate dosing can be achieved without any problems. Ho Functional aspects of the collapse valves 10...13 and operation of the device illustrated in FIG. The process will be explained according to FIG.

The point that can be pointed out with respect to FIG. P2 fills the hose-collapse valve when the pressure is released, and returns according to the diameter. This means that the collapse valve itself is returned to its original state.

Function and operation of hose-collapse valves 1o...13 of identical construction The process will be explained below with reference to FIG. 2, which completely shows the dosing cycle.

First, the closure closest to the end of the transfer hose 7 (Figure IL) - the collapse valve 13 is closed. I'm being teased. That is, via the conjugate control valve 13', the transfer hose 7 is supplied with the working pressure P3. is applied, and the transfer hose 7 is crushed. The pressure P2 acting within the pressurized container 3 is The synthetic material container 1 is pressurized, and this synthetic material container l itself transfers the transferred material into the transfer hose 7. Can be pushed. Closing - between the collapse valve 13 and the synthetic material container 1 the transfer hose 7 is connected to the transferred material. filled with. Closed - between the collapse valve 13 and the transfer hose end the transfer hose 7 is opened; ing.

At the next control pulse (Fig. 2), the double crush valve provided in the three directions of the pressurized container] 0°1 1 works. The transfer hose 7 is collapsed in the area of these two collapse valves 10, 11. It will be done. This forces a portion of the transferred material back into the synthetic material container l. Close here chain--in the area between the collapse valve 13 and the other two pressure-actuated collapse valves 10.11. A fixed amount of transferred substance is taken up.

Closing - To avoid end-side injection of transferred material when the collapse valve 13 opens, a pressure relief valve is used. The collapse valve, which acts as 11 and shuts off a certain volume on the return side, is relaxed.

The transferred substance taken under pressure partially fills the appropriate part of the transfer hose 7 ( (See Figure 3).

The actual dosing process then begins.

Closed - the collapse valve 13 is opened, which allows the transferred material to have a path to the end of the transfer hose 7. It is opened (Figure 4).

Here, the pressure relief valve 11 and the metering crush valve 12 which determine the transfer capacity are operated in sequence. and the previously separated or incorporated transport material continuum is extruded or (Figure 5). Subsequently, when the dosing and crushing valve 12 is opened again, the transfer hose 7 A suction effect occurs at the starting end of (see FIG. 6).

For the next dosing cycle, the closing-collapse valve 3 is activated again. Now the second closure - collapse Opening of the valve 10 causes the transferred substance to flow again.

(Collapse valve) The arrangement of 1 and 12 is to limit reverse suction (to a small capacity). Arrangements in pairwise order are also possible.

In this case, the metering parameters, i.e. the transfer speed and the transfer amount, are determined for the supply of air to the pressurized container 3. Restrictions and metering for - can be selected by appropriate selection of the crush valve 10. and changeable.

No. 311 (V) describes the transition from the synthetic material container 1 to the transfer hose 7. . The synthetic substance container l is equipped with a take-out I7 connection pipe 16 or a thin-walled position. Connected via November 7th, 1st. Therefore, the interior of the synthetic substance container 1 is sealed. , I keep it clean.4q;C. After inserting the synthetic substance container 1 into the pressurized container 3, remove it. The end of the outlet connecting pipe IG is cut at the thin wall position (shown by dotted line tr, -1-Yap). ), the transfer hose 7 is easily connected to the open end of the take-out I, 7 connection pipe l (j). It will be installed. Pressurized container 3 and synthetic material containers 11 and 11 (J, transfer hose 7 or equal) Because of the pressure behavior, the transfer hose 7 that is just attached (no pull-out force is exerted on it) I don't. Therefore, this hose connection does not require any other crushing ramps; The transfer hose 7 does not require special connecting elements.

Hose - Collapse Valve 10. ．． ．． An example of No. 13 is shown in FIG. This drawing As is clear, the transfer boss 7 is introduced into the collapse valve. This crush valve is called The guide hose 20 surrounds the housing 21 and extends through the housing 21. There is. This housing is connected via a pressurized hose 22 to a control valve io', .

13'. When this control valve operates, either the transfer hose 7 or the guide hose 20 crushed through the These guide hoses 20 can easily bypass the transfer hose 7. It is necessary to exchange the

According to the embodiment according to FIG. 5, the hose-collapse valve 10. ．． ．． +3 is with transport boss 7 are grouped together to form an integrated structure. This integral structural unit is Formed by inserting reinforced PCV-hose 25 into feed hose 7 . This PCV-hose then has its base on the inside corresponding to the number of four collapse valves. etc. (7 intervals along the line) are welded with the guide hose 7, so between these there are 151 ) between the weld seam 26 a pressurized chamber and a wall cavity are formed. Outer PCV-ho Fix the connection port 27 in the center against these wall air spaces in the space 25 and form the hole 28. If this occurs, the transfer hose 7 is compressed by the pressure load and closed (see dashed line). (see).

FIG. 6 shows a second embodiment of the device for pumping and distribution. synthetic material container is inserted into the pressurized container 3. The pressurized container 3, which is closed with a cover 2, is under pressure It is connected to the pressure generator 4 via a conduit 30 and a control valve 31 . synthetic material container 1 is connected to a transfer hose 7 in the same way as in the embodiment shown in FIG. This transfer hose is connected to a rotating hose pump 33 in the form of a hose pump 33. The housing 32 is passed through 1-v first. A hose according to the illustrated embodiment, ・The use of the tube 33 is particularly important when super-pressurizing the inside of the pressurized container 3 and the transfer hose 7 due to C action. This transfer hose 7 is constantly expanded by pressure, so that it can be used.

The illustrated hose pump 33 is equipped with a 4-) crushing lever 34 1, - These crushers transport the material to be transported in a manner according to the principle of a hose pump. -Pulse the sufu through τ4. At the end of the dosing cycle! −♂The hose pump 33 is 14 (see arrow), thus at the end of the transfer hose 7. Some degree of negative pressure is generated. The transferred substance present at the end of the transfer hose 7 is sucked back . To make the avoidance of droplet formation more effective, the end of the transfer hose 7 is provided with a small diameter. A type of nozzle 35 is inserted. This nozzle acts like a capillary tube. , sub-) 1 drop 6, if i is not formed 4°), replace this nozzle 35. It is also possible to use plugs that open and close elastically. In a favorable configuration , the diameter of the transfer bowl 7 is selected depending on the composition of the transferred substance and in this way the trailing drop shape is It is also possible to reliably prevent this from happening.

Can be used in combination with two co-extracted liquids according to figures 7 and 8 In each case, one dosing head 40 will be described. Both liquids are shown in Figure 1 or - their viscosity Depending on the difference in diameter, the material is transferred through a transfer hose of increasing diameter.

, these two transfer hoses 7,7' lead to a common distribution head 40, which The transport substance is released after R via the head. The flow of material to be transferred is within the distribution head 40. The motors 41 and 42 are activated at the same time. These motors 41 °42 is approximately 1. The shaft 43 is rotated at a rotation speed of IQ/sec. This main shaft 4 3 is.

number of - here two radial grooves 1. Each of these grooves The appropriate transport material is supplied. Next, each transferred substance belongs to an annular groove. Via different axial holes (distribution lines) 44 a distribution slit 45 is reached, where the odor The axial bore, which guides the transferred substance, is closed directly by the valve element.

The main shaft 43 is connected to the motor 41° above it via an insertable connection 46. It is combined with 42. If the coupling element consists of a permeable material, for example, the transported substance They are colored in various colors, so when rotating, the effect of light can be achieved by radiation or irradiation. Ru.

On the one hand, for specific various control of the collapse valve for the transferred material flow, and on the other hand Therefore, due to the specific behavior of the motor, in particular the transfer hose 7.7' corresponding to the transferred substance. A control mechanism is provided for coupling between the main shaft 43 and the main shaft 43.

Regarding the function of the system shown in Figure 7 - one main shaft 4 as shown only in the left corner of the drawing; Due to the rotation of 3, the generally continuous parallel flow of transported substances "A" and "B" is twisted. Alternatively, the two transported substances "A" and "B" are separated and flow in parallel. A substance that later passes under the main shaft 43, for example, is placed on a pan with a filling. I can't admit that. That is, the stoichiometry is adjusted via the pawnis pump. then These stoichiometric materials are twisted and discharged by the main shaft 43, that is, by its rotation.

The dispensing head described on the basis of FIG. and/or suitable for distributing mayonnaise. In contrast, as shown in Figure 8, The distribution head is suitable for distributing salad sauces, instant dressings or similar substances. There is.

The basic problem of the distribution head illustrated in Figure 8 corresponds to the problem of the distribution head according to Figure 7. do. However, unlike the embodiment according to FIG. The distributing head 40 consists of an integral cylindrical body 50; The cylindrical chamber 51 is connected to a transfer hose 7.7'. Inside this cylindrical chamber 51 A closing rod 52 is suspended in the middle 4.1 and axially symmetrically. This closes the cylindrical chamber 5 via the spring 53 and the closing flap 54. Transfer here When the substance is pumped into this cylindrical chamber 51, the closing flap 54 is lifted.

This allows the transferred substance to flow out. Next, the transfer (carrying) process ends I7 After that, the closing flap 54 is pulled back by the spring 53.

Figure 9 shows two basic diagrams, one of which is particularly suitable in combination with the configuration described above. A synthetic substance container 1 is shown. This synthetic material container 1 is generally manufactured using a pultrusion method. It is manufactured using a blow molding process, in which two ascending extrusions are The belt is formed in a two-part shell. Here, the implementation shown in Figure 9 By way of example, strip-shaped sheets with different thicknesses dl or d2, i.e. stiffness, especially filled The container hand portion 1a, which also has a filling capacity and a connection port 6, has a relatively thick wall (dl), so A strip of sheet shaped to be rigid and rigid is used.

In combination with the device for pumping and distribution according to the invention, the configuration of - The container hand part ib, which is soft or flexible due to the small thickness d2, is compared. and - as shown by arrow a, shrinks uniformly, so that the container eventually shrinks. It has the advantage that the contents are squeezed out well, ie without any residue. 9th In particular, from the drawings on the bottom of the figure it is clear how the flexible container hand part 1b is located there. It bends around the reverse groove 1a/b created by the process, and the rigid container hand part 1 is It can be clearly seen that it is in close contact with a.

Figure 1O shows the details of Figure 9 for the hose passage through the cover 2 of the pressurized container 3. (corresponding to part C). Filling and unloading connections for synthetic substance containers A guide 60 smaller than the outer diameter of the transfer hose 7 is bored in the cover 2 for the port 6. Therefore, the internal pressure inside the transfer hose 7 and the waist of the inserted transfer hose 7 The edge pressure caused by the return force of Ru.

FIG. 11 is a perspective view of the synthetic material container l. This synthetic material container has the same sea 1. material or, corresponding to FIG. 9, may consist of sheet materials of different stiffness. .

A special embodiment according to FIG. 11 provides that the synthetic substance container is equipped with a so-called flow line 65. This flow conduit is formed as a raised curved portion toward the outside of the container. There are 1. Via this flow line 65 a particularly good residue discharge is possible.

This flow conduit is illustrated in detail in FIG. 12 as a partial detail of FIG. 1I.

In this case, an almost completely empty synthetic substance container 1 is shown 17. withered The container wall is pressed against the wall with the filling and unloading connection [1G, and the remaining capacity is squeezed. It has been taken out and emptied. This residual volume is in particular supplied via the flow line 65 to the filling and removal I. 7 Escape to connection port 6. Particularly good residue extraction is achieved by forming around the synthetic material container l. A T-weld joint 1170 is made to contain the remaining contents and one last extruded annular By first forming the conduit 71, it becomes even more reliable. At this time, atrophy The fill/unload connection 16 is The extraction connection [1 is equipped with a notch 72, and therefore this notch is used for squeezing out the residue. It is very advantageous.

A novel dip tube 80 is shown in FIG. This dip tube serves as a filler for synthetic material containers. It is inserted tightly through the extraction connection port 6, and the transfer hose 7 is inserted into this immersion pipe. It has been inserted. This dip tube 80 has a number of holes 81 distributed over its entire length. have.

When the synthetic substance container l deflates, its wall abuts this dip tube 80 and thus the final Only a residual volume corresponding to the interior of this dip tube 80 remains. Then this dip tube 80 or inserted into a new synthetic container, the remaining residual volume is first drained. Ru. In this way, this dip tube 80 completely solves the problem of squeezing out the residue. Ru.

FIG. 14 shows an embodiment of a removal lance for a synthetic material container l. This la An outwardly closed protrusion 86 is molded in the known manner (German Union). (Refer to Japanese Republic Patent No. 39 28 855). This protrusion 86 has one layer (Fig. 14). As shown in FIG. 2, a handle 87 is provided which is supported on the monolithic synthetic material container l.

FIG. 15 shows the handling of the synthetic material container 1 during filling and squeezing.

To carry out the filling, the cap 88 of the protrusion 86 is cut (FIG. 1), thus removing the container. 1 can be filled. After the filling process is finished (FIG. 2) - reference number 89 See - 1 if the filling connection tube is open, i.e. in the open protrusion 86 or in the collapsed - welded seam 90. (Fig. 3). Here, to take out the contents of the container, take out the take-out lance 9. 1 is inserted into the protrusion 86 so as to cross the protrusion 86. See FIG. Removal lance 9I is a sealing gap between both wall portions of the protrusion 86 pierced by the formed tongue portion 92. be done. This sealing effect is achieved by the relatively thick container wall shown in Figure 9. Even better in the synthetic material container l. The protrusion 86 has a funnel-shaped curvature during manufacturing. It is advantageous to form a section 93, which curved section is an accurate guide for the extraction lance 91. This serves as the standard piercing position for accurate positioning. In this way, the hole 94 of the extraction lance 91 and a transfer hose 7 connected to this removal lance. Something is taken out or squeezed out.

The extraction lance 91 is pierced through both walls of the protrusion 86 so as to cross the protrusion 86. The advantage of the take-out part shown in Fig. 15 is that the take-out lance or container hand part is It has the advantage of not being pierced parallel to the split seam. Known in this regard Is there a problem with the configuration? This is because the thickness of the material varies within the area of the protrusion 86. This is because problems with sealing may occur.

The following points are added regarding the system shown in the drawings.

Transfer hose 7.7' of flexible synthetic container l to container filled with cleaning solution By slightly piercing the connection, the entire conveying conduit is cleaned. cracks are raw In some cases, the only place that may become unclean is the embodiment according to Fig. 7. This is the sealing part of the main shaft. However, this main shaft is easily unfixed and easily separated from the connecting part. It can be washed separately.

The following matters are of particular importance in connection with this invention.

- the viscosity is determined by applying pressure to a flexible synthetic container in a pressurized container; transferring liquids containing different degrees of and/or fractional components;- Adequate residue drainage is ensured by placing the flexible synthetic material container inside the pressurized container. It is proved.

Extremely convenient due to constant exchange of synthetic material containers and smooth transfer flow lines A suitable microbiological status is obtained.

- When a synthetic material container filled with the transferred material is pressurized with water, the non-surface area reduction and concomitantly extended retention of oxygen-sensitive products. (This is especially true for This applies to fractional extraction. ) In general, the following can be said.

Proper selection of synthetic container materials for many types of oxygen-sensitive filling materials The permeability of air oxygen must be kept low by selective selection and/or lamination. No. This applies to flexible synthetic containers that are filled and emptied without air. This is especially important in vessels. During partial unloading, the surface area is smaller than the filled volume. and therefore the originally good penetration values can deteriorate significantly depending on the degree of filling. There is a potential. This may occur under unfavorable working conditions (with only a small amount of remaining capacity). and long-term equipment in extremely sensitive filling materials) will eventually lead to functional failure. come.

This situation is addressed with other materials. For this reason, especially for transport containers, To perform the pressure loading, pressurized water is used instead of compressed air. Water - this is a place In some cases, it is even possible to control the temperature by circulating cooling. This results in a relatively high residence time in the open mouth state. For many foodstuffs We must ensure that the cold chain is uninterrupted before the product reaches the consumer. Therefore, an appropriate container material is selected in terms of price.
